WELCOME Hi there! Welcome to my gig, just now found the best gig for your c projects. I'm here to code your c programming app, I am Kerellos. I am working and learning c language for more than 2 years but I learned a lot and made very helpful and simple apps as smart calculator and more than 60 app   I will give you a smart calculator with steps for calculating first, it asks you to enter the numbers, and at the end inter = to start calculating then give you the answer by following: X is multiplication D is dividing XX3 (for example) means that multiplying is the third sign DD5 (for example) means that the dividing is the fifth sign X+D means (multiplication + dividing) 0+ means the sum of (multiplication and dividing) + the first number 01 or 11 or 41 the number 1 means that it adds numbers 02 or 12 or 42 the number 2 means that it subtracts the number and the 0 or 1 or 2 or 3 that before add or subtract is the number of signs (+ or -)   the result will appear at the last of the window (last number shown)   Feel free to inbox me before ordering to discuss the project in detail Stay blessed. Thanks
